CVE-2025-38617: net/packet: fix a race in packet_set_ring() and packet_notifier()

Published Aug 22, 2025
·
Updated

In the Linux kernel, the following vulnerability has been resolved:

net/packet: fix a race in packetsetring() and packetnotifier()

When packetsetring() releases po->bindlock, another thread can run packetnotifier() and process an NETDEVUP event.

This race and the fix are both similar to that of commit 15fe076edea7 ("net/packet: fix a race in packetbind() and packetnotifier()").

There too the packetnotifier NETDEVUP event managed to run while a po->bindlock critical section had to be temporarily released. And the fix was similarly to temporarily set po->num to zero to keep the socket unhooked until the lock is retaken.

The po->bindlock in packetsetring and packetnotifier precede the introduction of git history.
